With friends, family or colleagues, we never say no to foosball. Everyone has to do his job in order for the ball to go through the opponent's goal. Teamwork is the most importing thing while playing foosball. Everyone need to grab a stick and do his best to keep the ball.
When you do not have a real one at home, you still have the virtual one. The principle is the same: to score goals as much as possible against an opponent. The good thing about the online foosball online it's that it is free!
